PIPE-HANGER.

SPECIFICATION'forming part of Letters Patent No. 497,512, dated May 16,1893.

Application filed October 31, 1892. Serial No. 450.563. (No model.)

To aZZ whom it may concern.-

Be it known that I, ALLAN J. BEATON, a citizen of the United States,residing at New Britain, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements in PipeHangers, of which the following is a specification.

My invention relates to improvements in pipe hangers, and the objects ofmy improvements are simplicity of construction and eficiency andconvenience of the article which is especially adapted for hanging pipesto ceilings or overhead supports.

In the accompanying drawings, Figure lis a side elevation of my pipehanger in its closed position. Fig. 2 is a horizontal section thereof onthe line x of Fig. l. Fig. 3 is a side elevation of the same, partly insection, as opened for the reception of a pipe,

and Fig. 4 is a side elevation showing a modification.

A designates a screw shank which is designed to be screwed into someoverhead supi port, or if desired a vertical one.

B designates a jaw which is integral with said shank and which isdesigned to embrace or surround a little vmore than half of the pipe.

C designates a companion jaw which is hinged or pivoted to the shank Aas at 3, and D designates a fastening ring for lockingthe jaws together.

On each of the jaws I form a lateral pro'- jection or boss 4 at a pointbelow the pivot 3. The ring D I form with lateral projections 5 atdiametrically opposite points, which projections are co-incidentinposition with the bosses 4. These projections 5 in the ring are recessedon their inner faces so that the bosses 4 on the jaws may pass throughthem when the rin gisset to register therewith. The body of the ring Dbetween these projections sets' close enough to the jaws so that saidbosses project beyond the inner face of the ring. I prefer to form thetop of the ring of a cam shape as shown. When the jaws are closed thering may be brought to apoint below the bosses 4 and then turned to makeits upper edge engage with the under sides of 5o the bosses so that thering is held down firmly for holding the jaws in their closed positions.By turning the ring so that the projections 5 co-incide with the bosses4, the ring may be raised above said bosses and above the pivot of thejaws and the jaws may be open as shown in Fig. 3. The jaw B is extendedaround so as to embrace more than half the circumference ofV the pipe,or in other words it extends beyond a vertical line passing through theaxis of the shank so that a pipe laid therein as the jaws are open willnot have a tendency to roll out even if the jaw C is not closed. Afterplacing the pipe within the jaw B for supporting it, the jaw C isbrought down into the position shown in Fig. l, and the ring D again letdown below the bosses 4, when it is turned a partial rotation to engageits upper edge with the under sides of said bosses as shown in Figs. land 2, thereby Iirmlysecuring the pipe within the hanger againstaccidental displacement.

While I prefer employing the ring with the projections in connectionwith the holding boss, it is evident that I may employ a plain ring D asshown in Fig. 4, which instead of being looked down will be held inposition by gravity for securing the jaws inplace. It is also evidentthat I may if desired divide the jaws near a vertical line passingthrough the axis of the shank as shown in Fig. 4, but I preferablydivide them as shown in Figs. 1 and 3.

In Vorder to provide for the sliding of the pipe longitudinally withinthe hanger, as for instance under the expansion and contraction of themetal, the loose rings 6 may be fitted to the lower part of the hangerto rotate thereon in a reduced or grooved portion as shown in Figs. land 2, but said rings may be omitted without changing the other featuresof my improvement. These rings may be formed on the jaw B by separatelyforming said rings, placing them in the mold for the jaws and castingthe jaw within them, the rings being coated so as to be loose aftercasting in the ordinary manner of casting other articles with loosepieces thereon.

By my improvements I form a simple and inexpensive pipe hanger, which isVery convenient and efficient in use.

I claim as my invention- 1. The herein described pipe hanger con- IOOsisting of a screw shank, Jshe jfLWB made rigid therewith, the jaw Chaving a straight portion corresponding with the lower part of saidshank and bywhieh i@ is pivoted thereon, and the holding ring arrangedon said straight portions and adapted to slide below the pivot of saidjaws, substantially as described and for the purpose specified.

2. A pipe hanger consisting of pivoted jaws, a supporting shank and nlocking ring, xc the jaws being provided with laterally projectingbosses 4 and the ring being provided with Lhereeessed proj eotious 5,substantially as described and for the purpose specified. ALLAN J.BEATON. Witnesses:
